Definition:
1. Ta is ambient temperature.
2. F is a pixel readout rate. It is double of the clock frequency.
3. Tint is an integration time or line scanning time. In the B/W operation mode, it is determined
by the interval between two start pulses. For the color operation mode, Tint is at least three
times that of the B/W mode.
4. Vpc(n) is the effective output signal of each pixel. It is defined by:
Vpc = Vp(n) – Vd(n)
Vp (n) is the output signal of nth pixel in the white paper.
Vd (n) is the output signal of nth pixel in the dark paper.
